DISK DRILL.

SPECIFICATION forming part of Letters Patent No. 734,016, dated July 21, 1903. Application filed January 22, 1903- Serial No. 140,143. (No model.)

To all whom, it may concern:

Be it known that LWILLARD A.VAN BRUNT, a resident of Horicon, in the county of Dodge and State of Wisconsin, have invented certain new and useful Improvements in Disk Drills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in disk drills, and more particularly to that class of drills known as double-disk, the object of the invention being to provide improved bearings which will take up but small space, are easily lubricated, and can be removed and replaced at will.

With this object in view the invention consists in certain-novel features of construction and combinations and arrangements of parts,- as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a View in vertical section, illustrating my im provements. Fig. 2 is a view in vertical section, taken through the center of Fig. 1. Figs. 3 and 4-. are views illustrating details of construction. Figs. 5 and 6 are views of slightlymodified constructions; and Fig. 7 is a view in vertical section, illustrating the manner of securing the parts together.

1 represents a cast-metal frame having a tubular channel 2 forthe dropping of grain between the disks and made with a depending arm 3, to which the disk bearing-blocks 13 are secured, as will be hereinafter explained.

The frame 1 has a forwardly-projecting member 5, to which 'the lifting and drag bars (not shown) are connected, and a rearward extension 6 is also provided on the frame and made with a curved lug 7, against which the scraper 8 is secured by means of a set-screw 9. This set-screw 9 is passed through an opening in the scraper, through a slot in lug 7, and into a nut 9, supported in an elongated pocket 10 in lug 7 and movable therein to permit of adjustment of the scraper to best perform its functions, it being understood that the scraper isfor bothldisks and has its side edges inclined to conform to the incline or set of the disks.

The sides of arm 3 at its lower end are flatsurfaced at such an incline as to hold the disks at just the proper angle when secured thereagainst and is made hollow or with a central duct 11 for the passage of lubricant to the bearings. Into screw-threaded openings in opposite sides of arm 3 at its lower end the threaded hollow lugs 12 of circular bearing-blocks 13 are screwed after being screw-threaded central openings 17 for the admission of a tool to turn blocks 13, and this opening is closed by a plug 18 or other suitable means. Lubricant may also be inserted through the opening 17 to the bearing, and the opening affords a means for inspecting the hearing at any time.

Instead of providing screw-threaded lugs on the bearing-blocks 13 I may provide arm 3 on its opposite sides with screw-threaded lugs 19 to enter sockets in the blocks, as shown in Fig. 5, or I might provide independent hollow screws 20 to couple the blocks and arm,

as shown in Fig. 6.

In all of the forms described it will be ob-' 13 in cups 16, and lubricant-pockets 22 are.

made in the blocks to retain the desired amount of lubricant and feed it to the bearing.

By so constructing myimprovements it will be seen that the bearings take up but little space, thus permitting a large number of disks to be used on a machine; The bearings can be lubricated from the top by=pouring the lubricant into ducts 11, and the parts can be easily separated and assembled and damaged parts replaced with but slight expense.

Various other changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not confine myself to the precise details set forth,but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a disk drill, the combination with a support, two disks and bearings for said disks, of right and left hand screws connecting the respective bearings with the support.

2. In a disk drill, the combination with a support and disks at respective sides thereof, a bearing-block for each disk, a right-hand screw connecting one of said bearing-blocks with the support and a left-hand screw connecting the other bearing-block with the support.

3. In a disk drill, the combination with a support having transverse openings at its lower end and two disks, of bearing-blocks secured in said openings and overlapping the outer faces of the disks, and cups inclosing said bearing-blocks and secured to the disks.

4. In a disk drill, the combination with a support having transverse openings at its lower end and disks at opposite sides of said support, of bearingblocks overlapping the outer faces of the disks and having right and left hand threaded portions respectively entering the transverse holes of the standard and cups inclosing said bearing-blocks and secured to the disks.

5. In a disk drill, the combination with a support having a lubricant-duct therein, and disks at opposite sides of said support,of bearing-blades secured to opposite sides of the support and overlapping the outer faces of the disks, said blocks having lubricant-ducts therein communicating with the duct in the support and cups inclosing said blocks and secured to the disks.

6. In a disk drill, the combination with a support comprising a hollow arm, a rearward extension having a scraper-seat at its rear end, said rearward extension having an elongated pocket coincident with said scraperseat, and a grain-dropping tube between the hollow arm and the rearward. extension, of rotary disks at opposite sides of the support, a scraper between the disks and having its upper portion resting on said seat, a bolt passing through the scraper and a head on said bolt located in said elongated pocket.

7. In a disk drill, the combination with a support having a lubricant-passage therein, and two disks, of bearing-blocks detachably secured to opposite sides of the support and overlapping the disks, said blocks having inbricant-ducts communicating with the passage in the support and cups inclosing said blocks and secured to the disks.

8. In a disk drill, the combination with a support and a disk, of a bearing-block secured to said support, overlapping the face of the disk and havinga bearing on which the disk turns, said bearing also having an angular opening for the reception of a wrench, a cup inclosing the block and having an opening to turn on the blocks and disposed at an angle to each other, cups inclosing the blocks and secured to the disks and lubricatingchambers between said blocks and cups, and communicating with lubricant-duct in the support.

10. In a disk drill, the combination with a support, of bearing-blocks having threaded lugs screwed into said support after passing through the disks, said disks mounted to turn on circular enlargements of the blocks, cups inclosing the blocks and secured to the disks, and means closing openings in the cups.

11. In a disk drill, the combination with a support having a lubricant-passage therein, of bearing-blocks having a threaded connection with opposite sides of the support, disks turning on said blocks, cups secured to the disks and inclosing the blocks and lubricantducts communicating with the passage in the support and said cups.

12. In. a disk drill, the combination with a support, of bearing-blocks having a threaded connection with opposite sides of the support, disks mounted to turn on the blocks and disposed at an angle to each other, cups inclosing the blocks and secured to the disks and means for closing openings in the cups through which openings a suitable tool may be inserted to remove or attach the blocks.

13.. In a disk drill, the combination with a support, of a bearing-block, a screw-threaded lug on the block screwed into the support by turning toward the forward edge thereof, and a disk turning on said block and tending to tighten the block to the support.

14. In a disk drill, the combination with a support, of bearing-blocks, screw-threaded lugs on the blocks screwed into opposite sides of the support by turning both toward the forward edge thereof, and disks turning on the blocks and tending to always tighten the blocks in place.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

WILLARD A. VAN BRUNT.
